Usually 3.3V – 4.8V (calculated based on current and resistance), though it operates on 12V/24V systems via current-limiting drivers Frame Size: NEMA 17 (42 x 42 mm) Body Length: 34 mm Shaft Diameter: 5 mm ("D" shape) Weight: ~215g Key Operational Features Creality Ender 3 Stock Factory Vref · GitHub bj42d15 26v10 stepper motor datasheet

At 1.0 Amps, this small motor will get warm (around 50°C - 60°C) after extended use. This is completely normal and safe (the insulation class is 130°C). However, if you accidentally set your driver to 2.0A, the motor will overheat, the magnets will demagnetize, and the motor will permanently lose torque.

(like the Ender 3 series). While detailed official datasheets are often difficult to find, technical communities and manufacturer documentation for near-identical variants (like the 26V09 or 26V12) provide the following specifications: Technical Specifications Step Angle : 1.8° (200 steps per revolution). Rated Current 0.84A per phase Input Voltage : Maximum 24V DC. Phase Voltage (Nominal) Holding Torque : Approximately 2.86 kg·cm (0.28 N·m). Inductance : ~9.3 mH. Resistance : ~5.75 Ω. Physical Dimensions While wire colors can change depending on the

M3 threaded holes spaced 31mm apart from center to center.

To use the BJ42D15-26V10, you must connect it to a compatible stepper motor driver, such as the A4988, DRV8825, or TMC2209. The most critical aspect of this process is correctly setting the driver's to ensure the motor operates properly without overheating. However, if you accidentally set your driver to 2

The BJ42D15 series uses a standard configuration. Correctly identifying the two separate motor coils (winding pairs) is critical for proper operation. While color codes can vary between manufacturers, the following is the most common arrangement found in the BJ42D15 series.

| Parameter | Value | |------------------------|---------------------------| | Rated voltage | 26 V DC | | Winding resistance | 10 Ω ±10% | | Rated current (calculated) | 2.6 A (using I = V/R) | | Inductance (typical) | 4–8 mH (assumed) | | Insulation class | B (130°C) | | Dielectric strength | 500 V AC for 1 min |
